Just realized I made a mistake Reading.
In chapter 5.3.4.4 The Signature Information itâs used an example without
<ext:ExtensionURI>.
In chapter 5.3.4.8 A Signature Skeleton itâs used another example without
<ext:ExtensionURI>.
Of course <ext:ExtensionURI>
itâs not used because only
<ext:ExtensionContent> is the shown.
Iâm sorry about this mistake the other doubts remain.

Subject: Urgent clarification regarding enveloped signature
Hi all!
I was Reading documentation regarding digital signature in this link
http://docs.oasis-open.org/ubl/os-UBL-2.1/UBL-2.1.html#S-UBL-DIGITAL-SIGNATURES
In chapter 5.3.4.1 The Extension Metadata
it seems element <ext:ExtensionURI> with value âurn:oasis:names:specification:ubl:dsig:envelopedâ
is mandatory.
In chapter 5.3.4.4 The Signature Information itâs used an example without
<ext:ExtensionURI>.
In chapter 5.3.4.8 A Signature Skeleton itâs used another example without
<ext:ExtensionURI>.
In chapter 5.4 Digital Signature Examples
itâs used another example without <ext:ExtensionURI>.
In chapter 6.2 Digital Signature Conformance
itâs mentioned that âClaiming syntax conformance to the enveloped signature profile of UBL 2.1 requires (â) the <ext:Extension> element
is present in the UBL extension and has either urn:âoasis:ânames:âspecification:âubl:âdsig:âenveloped or urn:âoasis:ânames:âspecification:âubl:âdsig:âenveloped:âxades as
its valueâ.
My doubts:
If <ext:ExtensionURI> is mandatory, was it forgotten in the examples? Are the examples
right?
If for conformance reason <ext:Extension> is
required to have a value why is it never mentioned?
Is it a mistake and you really mean that
<ext:ExtensionURI>
is required to have a value?
Are you considering that <ext:ExtensionURI>
value is <ext:Extension> value?
Please accept my apologies if this is just a misunderstanding from my part due to English not being my native language.
Best regards
